STOVE-LID.

Speclcation of Letters Patent.

Patented Nov. 10, 191e.

To all whom it may concern Be it known that I` NoiiMAN E. Rios, a citizen of the United States, and a resident of Eureka, county of Humboldt, and State of California, have made certain new and useful Im roveinents in Stove- Lids, of which the ollowing is a specification.

This invention relates to an improvement in stove lids, and one of the principal ob- 'ects of the invention is to rovide a stove id by means of which a coo ring vessel may be supported ont of direct contact with the stove top, and thus scorching or burning of the contents of the vessel may be prevented.

A further object of the invention contemplates the formation, as a result of the novel construction of the lid, of a double hot air chamber which will be in direct communication with the bottom of the cooking vessel, whereb the vessel will be subject not to the direct eat of the stove top, but to the heated air contained in the chamber.

Another object of the invention is the rovision of a stove lid of the class descri ed, which will be extremely simple, durable, eicient in operation, and inexpensive to manufacture.

lVith these and other objects in view which will become apparent as the descri tion proceeds, the invention resides in tie construction, combination and arrangement of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawing in which like characters of reference indicate like parts throughout the figures, of which,

Figure 1 represents a top lan view of a stove lid constructed according to my invention, Fig. 2 represents a vertical transverse sectional view therethrough, showing the same in position on a stove, and Fig. 3 represents a vertical transverse sectional view taken through a stove lid constructed according to my invention, and showing how the same may be formed of separate members.

Referrin more particularly to the drawing, the li com rises a flat circular plate provided centra ly thereof with an openin 6, and provided around its outer edge witli an upwardly extending annular fian e 7, and furt er rovided with a plurality o radially dispose upwardly extendin ribs 8, somewhat eater in width at their bottom than at their top, said ribs being of the saine height as flange T, and extending from said flange at spaced intervals to the central opening (i of plate 5. A second circulai p ate t) which is somewhat less in diameter than the plate 5, foriiis the bottom of the lid, and is connected by an annular wall l0 to the plate 5 in parallel and spaced relation therewlth, and the wall 10 is disposed at right angles to the plate 5, and is positioned inwardly of the outer edges thereof, so that. a shoulder 11 extending around the lid is formed, and which is adapted to rest against the flanged portion 12 of a stove top 13, whercb? the lid may be positioned on the top. Ilange 12 as will be understood surrounds tlie lid opening in the stove top. The relation of the flanged portion 12 with the top 13, as shown in the drawing, illustrates the Ordinar manner of constructing the top, and as s own the flanged portion 12 occurs in a horizontal plane somewhat below the horizontal plane of the surface of the stove top, and the height of flange 7 and ribs 8 is such, that when in position on the stove, the upper edges of said fiance and ribs will be flush with the upper sur ace of the stove top. The plate 5 may be provided at a suitable point with an opening 14 for receiving a stove lifter.

In the construction shown in Figs. 1 and 2, the lid is cast in a single piece, but in Fig. 8 has been shown a lid formed of an upper and lower section, the upper section comprising the plate 5, flange 7 and ribs 8, and the lower section comprising the lower plate 9 and the wall 10. The sections are connected by a plurality of threaded studs or bolts 15 which pass through the upper and lower lates, and position the same in the saine re ation as when the lid is cast in one piece said studs being provided with nuts in the usual manner. lhe space inclosed between plates 5 and l) and the circular wall 10, forms what may be termed a lower hot air chamber A, and as will be readil understood when a cooking vessel is place upon the stove lid. the spaces inclosed by the flange 7 and ribs 8 form what may be termed a second upper hot air chamber B, one wall of which is formed by the bottom of the cooking vessel, so that the vessel is not' in direct contact with the stove top, or with any directly heated metal, but is subJect to the heated air contained within the hot air chambers of the rib.

It has been found that when a cooking utensil is placed over a lid constructed according to my invention, by reason of the `vessel not coming into Contact with directly heated metal, but only with the heated air, the contents of the vessel are less apt to scorch or burn. By having the uppermost edges of the lid fiush with the top of the stove, the cooking vessels positioned on the store top, may be freely moved about, which would not be the case were the lid projecting above the surface of the top.

Although I have described the preferred embodiment of my invention, I may desire to make suoli changes in the construction, combination and arrangement of parts thereof as do not departl from the spirit of the invention, and the scope of the appended claims.

I claim:-

1. A stove lid comprising a circular plate having an opening centrally therein, an u wardly rojecting Continuous flange on tiie outer e ge of said plate, radially disposed ribs extending.,T from said flange to the openi ing in said plate, a second imperforate plate of less diameter than first said plate, and a wall eonneetiiw second said plate in parallel and spaced relation with first said plate, said wall occurring inwardly of the edges of first said plate whereby a supportin shoulder for the lid is formed.

A stove lid having a lower air chamber whose base and side walls are imperforate, a

Ytop plate on said chamber, and having a if re at ively large central opening forming the only vent to or from said air chamber, an upwardly projecting continuous outer rim flange on said top plate, and projections on said plate within the flange the lower air f cham )er operating to prevent the passage of flame from below to a vessel supported on the 11d.
